NRPE aka Nagios Remote Plugin Executor, allows us to monitor the local resources of a Linux host on Nagios monitoring server. It needs to be installed on both Linux host & on Nagios server. So let’s start with configuring Linux host first.

Verifying Nagios configuration file

If there are any errors, resolve them & then restart the nagios server for changes to take effect.

$ service nagios restart

Open web-console

Open your web-console, by typing your nagios IP address or FQDN in your browser & enter credentials for nagios. Once inside the web-console, goto services page & you should see that services for your Linux hosts have added here for monitoring .

So, this was our tutorial on how to add Linux hosts to Nagios server for monitoring. If you have any queries or comments, please mention them on the comment box down below.
